Cuesheet rows are virtualized (react-virtuoso), so rows scrolling out
of the small overscan buffer get unmounted, destroying their <img>
elements; scrolling back remounts them from scratch. Native
loading='lazy' on the image compounded this with an extra deferred
load on every remount. Widen the overscan buffer and drop the
redundant lazy attribute so images stay mounted through normal
scroll-and-back gestures.
